Brandon needs to mow her lawn. To make sure requires 5 gallons of gas for every 2 gallons of oil. How much oil will she need for 8 gallons of gas? Your answer should be in tenths.

Answer 1

To calculate the amount of oil needed for 8 gallons of gas, we need to use the given ratio of 5 gallons of gas to 2 gallons of oil.

First, let's find the ratio by dividing the total amount of gas by the ratio of gas to oil:
8 gallons of gas ÷ 5/2 gallons of oil = (8/1) ÷ (5/2) = (8/1) * (2/5) = 16/5 = 3.2.

Therefore, she will need 3.2 gallons of oil for 8 gallons of gas, or 3.2 tenths.
